I got a call from the machine shop after 5 weeks. They wanted me to come in to discuss what they had found. THey did a leakdown test and found cylinders 3 and 7 were leaking 90%. They pulled that cylinder head and found 2 sticky exhaust valves and excessivly cut valve seats. The heads were purchased from Areohead Racing many years ago. That head needed a couple new valves, all new valve seats and new guides. The other head was working OK but I didn't trust it. It would have needed the same work. I decided to bring in the original heads instead of trying to fix those.
A couple days after dropping off the original heads, I went in to see what they found with those. Those heads needed all new valves, guides and one valve seat. Right as I was leaving, the manager said,"Oh, by the way, the intake manifold is cracked." He took be back to see the intake and sure enough. There was a big crack starting in the choke thermostat well and extending all the way over to the EGR valve opening. That was the original intake with the correct casting date. Luckily I had a spare intake that checked out good. The new intake is slightly different but it's close.
I picked up the engine last Tuesday.
Cleaned and painted it on Wednesday.
Dropped it back in on Thursday.
I worked on it Friday night and most of the day on Saturday. After everything was put back together, I installed the new repro green top battery and it fired right off. I was tired so I havn't timed it yet but it runs and sound decent. Here's a quick video I took of it running.
